Products that do what Tandem – An Engine for Secure Multi-Party Computation (Written in Rust) does
Tandem is a cryptographic engine for executing programs using Secure Multi-Party Computation (MPC), which allows 2 parties to compute a function without revealing their private inputs. The classic example from cryptography is the millionaires' problem, where two millionaires compute who is richer without revealing their wealth to each other. MPC has in the past been mostly confined to academia, but thanks to some recent papers has finally become fast enough for practical applications. Tandem uses Garbled Circuits, encrypted circuits consisting of boolean gates. While there have been other…

forkrun is the culmination of a 10-year-long journey focused on "how to make shell parallelization fast". What started as a standard "fork jobs in a loop" has turned into a lock-free, CAS-retry-loop-free, SIMD-accelerated, self-tuning, NUMA aware shell-based stream parallelization engine that is (mostly) a drop-in replacement for xargs -P and GNU parallel. On my 14-core/28-thread i9-7940x, forkrun achieves: * 200,000+ batch dispatches/sec (vs ~500 for GNU Parallel) * ~95–99% CPU utilization across all 28 logical cores, even when the workload is non-existant (bash no-ops / `:`)…

Hi HN, I'm Dan Draper, founder of CipherStash. We've spent 5 years building per-value searchable encryption tech. We realized that encryption like this is incredibly powerful but the engineering required is generally not worth the effort. So we built a platform and opensource SDK to take the cry out of cryptography :) CipherStash Stack is: * A searchable encryption SDK for TS and Postgres * Fast, key management with Zerokms (backed by HSM) * A transparent SQL proxy * Auth library and OIDC federation service * Skills for data security Integrations include Prisma Next, Drizzle, Auth0, Clerk…

Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

We needed a secure, multi-tenant way to offer shell accounts to users, but most VMMs were using too much memory and containers are unsafe. With clone, VMs are now more memory efficient than containers in most cases. Since many other projects on HN looked like they were doing this too, open sourcing this was the right thing to do. Feel free to use in whole or in part as you see fit!

I’ve developed a new public-key encryption scheme (DIAC) that uses multidimensional, high-precision complex keyspaces and a modular trapdoor function for ultra-high entropy and quantum resistance. The code, benchmarks, and research paper (PDF) are all open-source: https://osf.io/mvkcq/ Would love feedback, questions, or cryptanalysis!

Homomorphic encryption enables computations to be performed directly on encrypted data without requiring access to the private key. This allows data to be securely stored in the cloud while still being processed using the cloud’s computational power. Meanwhile, the cloud remains unaware of the actual data it is handling. Although fully homomorphic encryption has become available in recent years, when considering performance trade-offs, partially homomorphic encryption proves to be a more efficient and practical choice. It is significantly faster, requires fewer computational resources, and…

Hey HN, I'm Willem from Confident Security, we've built CONFSEC, a provably private AI inference engine. Today, we're excited to open-source twoway: https://github.com/confidentsecurity/twoway twoway is a Go package that makes it easy to implement secure, encrypted request-response flows. It powers CONFSEC's blind prompt handling, ensuring no one, not even us, can see client requests. We built twoway on Cloudflare's circl/hpke, it uses Hybrid Public key Encryption to implement two flows: - A one-to-one flow where a sender communicates with a single receiver. This…

Hi HN, I'd like to share DualMix128, a pseudo-random number generator I developed. It's written in C and achieves very high speed while maintaining strong statistical properties for non-cryptographic use. GitHub (MIT License): https://github.com/the-othernet/DualMix128 Key points: * *Fast:* Benchmarked at ~0.36 ns per 64-bit generation on GCC 11.4 (-O3 -march=native). This was over 2x faster than `xoroshiro128++` (~0.74 ns) and competitive with `wyrand` (~0.36 ns) in the same tests. (Benchmark code/results in repo). * *Robust:* Passes the full TestU01 BigCrush suite…

Lilith Zero is a high-performance security runtime designed to mitigate data exfiltration and unauthorized tool invocation in LLM-based agent systems. By interposing at the transport layer, Lilith Zero enforces security invariants through deterministic policy evaluation and strictly framed execution. Lilith Zero is OS, framework, and language agnostic, providing uniform security primitives across diverse implementation environments.

https://github.com/seanwevans/lockstep I want to share my work-in-progress systems language with a v0.1.0 release of Lockstep. It is a data-oriented systems programming language designed for high-throughput, deterministic compute pipelines. I built Lockstep to bridge the gap between the productivity of C and the execution efficiency of GPU compute shaders. Instead of traditional control flow, Lockstep enforces straight-line SIMD execution. You will not find any if, for, or while statements inside compute kernels; branching is entirely replaced by hardware-native masking…

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…
